Generally speaking, IPL is more effective at treating large areas, while lasers are better for localized hair removal.
Conversely, IPL will yield better results if you have pale skin and light hair..
What is invisible laser radiation?
Laser radiation is an optical radiation that can either be visible or invisible. … Invisible laser radiation is mostly infrared radiation, but UV-lasers also exist. Laser with an invisible beam is dangerous because when a person cannot see it, they cannot sense danger.
Can laser give you cancer?
Different lasers are used to treat sun damage and wrinkles. The lasers used in hair removal or other skin procedures have such a minimal amount of radiation. Plus, the minimal amount is only being exacted on the surface of the skin. So, they don’t pose a risk of cancer.
Is 100 mW laser dangerous?
As consumers obtain more powerful lasers, the hazard distances (NOHD, visual interference) increase less than one might expect. A laser 100 times as powerful is not 100 times as dangerous; it is “only” 10 times as dangerous, assuming the divergence is the same.
What are the properties of laser radiation?
Laser Radiation Properties ILaser radiation is nearly monochromatic. Monochromatic refers to a single wavelength, or “one color” of light. … Laser radiation is highly directional. … Laser radiation is highly coherent, which means the waves of light emitted have a constant relative phase.
Which color laser is most dangerous?
green laserLike any lasers, pointing a green laser at one’s eye can be extremely dangerous and can causer permanent retinal damage. Humans can more easily see the beam of a green laser than a red laser because the human eye is more sensitive at low light levels, which are levels in the green region of the light spectrum.
